嵌入的ImageView滚动型与自动布局在iOS 6 [英] Embed ImageView in ScrollView with Auto Layout on iOS 6

问题描述

我想做出非常简单的元素与新的iOS自动布局6 SDK。
我有一个ImageView的和滚动型嵌入它。 （一切建立与界面生成器）。该PNG文件设置和ImageView的模式被设定为左上

I am trying to make very simple element with new iOS 6 SDK with auto layout. I have an ImageView and Embed it in ScrollView. (everything build with Interface Builder). The .png file is set and imageView mode is set to "Top Left".

实施

#import "ImaginariumViewController.h"

@interface ImaginariumViewController ()
@property (weak, nonatomic) IBOutlet UIScrollView *scrollView;
@property (weak, nonatomic) IBOutlet UIImageView *imageView;
@end

@implementation ImaginariumViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.scrollView.contentSize = self.imageView.image.size;
    self.imageView.frame =
    CGRectMake(0, 0, self.imageView.image.size.width, self.imageView.image.size.height);
}

@end

当我运行应用程序，图像不滚动。做自动布局都是一样的关闭（使用Struts和弹簧），我有工作滚动。
我想这个问题是制约因素。任何人可以帮助我，好吗？

When I run the app, the image is not scrolled. Doing all the same with auto layout turned off (with struts and springs), I have working scrolling. I guess the problem is with constraints. Could anybody help me, please?

推荐答案

我刚遇到我是更新教程同样的问题。我试图删除编程的限制，骂，以及敲我的头撞墙 - 没有运气

I just encountered the same issue in a tutorial that I was updating. I attempted programmatically deleting constraints, cursing, and banging my head against the wall - no luck.

大约5分钟前，不过，我试过的东西，有固定的我遇到的另外一个问题，并ただ！ UIScrollView的再次合作！解决的办法是移动老code表示的UIScrollView contentSize属性设置成viewDidAppear的实现，而不是viewDidLoad中：

About 5 minutes ago, however, I tried something that had fixed another issue I encountered, and, ta da! UIScrollView is working again! The solution was to move the old code that sets the UIScrollView contentSize property into an implementation of viewDidAppear, rather than viewDidLoad:

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    self.theScroller.contentSize=CGSizeMake(200.0,2000.0);
}

我希望这可以帮助别人遇到了一些已经出现了自动布局的烦恼。

I hope this helps someone else encountering some of the headaches that have appeared with Auto Layout.
